You just need to insert the module named "NVMeExpressDxE.ffs". The other module named "SAMSUNG_M2_DXE.ffs" only supports M.2 connected Samsung SSDs, which do support AHCI (e.g. the SM951 AHCI) and not NVMe.

(By "correctly" modding the bios, I am hoping to be able to ""see"" the Samsung 950 as an available hard drive via the adapter card in a PCIEX16 slot within the bios screen! Secondarily, I'll add the necessary driver etc to my existing imaged SSD W10 & W7 OS's, as well portrayed on YouTube!)

Although you will not see the SSD within your BIOS, you will be able to boot off it.Preconditions:1. You have to enable the required BIOS settings, which allow you to boot in UEFI mode.2. The bootable DVD or USB Flash Drive has to support the GUIMODE Partition Table (instead of the Master Boot Record).3. You have to install the OS in UEFI mode (the bootable DVD/USB Flash Drive should be shown with the prefix "(UEFI)".

Hi Fernando, i'm new here. Thank you for your guide. I followed it to get NVMe support in my Asrock z87 pro 4 board and i succeed but i have a problem. After flashing bios, i've installed windows 10 in UEFI mode and i can boot from my samsung 950 pro without issues. I'm using a Lycom DT-120, PCIe 3.0 x4 Host Adapter plugged on a pcie 2.0 x16 slot because my main 3.0 x16 is busy with an AMD r9 fury. I've download samsung magician and NVME drivers from samsung website and installed. The problem is that im getting slow speeds and i don't know why. Used both magician and crystal disk mark and speed is about 800 mb/s both sequential reading and writing. I have also an 850 evo running on sata 3 and is much faster than my 950 pro and it should not be (about 4000mbps reading and 3500 writing using rapid mode of course). Maybe i miss something to get better speed?

I read the guide, my mobo is p8z68 v pro gen 3 with the BIOS 3802 released in 2015 BUT it does not support booting from efi compatible pci rom. Only Legacy rom. So does it mean i cant boot use nvme ssd as bootable drive? Even if i add Bios needed files into the most recent bios of my mobo.

I recommend to uninstall Samsung's Magician (by the way: the "RAPID mode" has no impact on the real SSD speed) and to replace Samsung's NVMe driver by the generic Win10 NVMe driver (provided, that your OS is Win10).If these actions should not solve your performance problems, try the following:Remove your discrete graphics card and use temporarily the Intel iGPU instead, insert the PCIe adapter into the PCIe 3.0 x16 slot and check the performance of your NVMe SSD again.This way you will get knowledge about the origin of your performance problem.

To answer this question I need some additional informations:1. Have you inserted any NVMe EFI module into the BIOS of your mainboard? 2. If yes, which one?2. How did you check, that you cannot boot into the SSD in UEFI mode?3. Are you sure, that your Intel 600P SSD is supported by any of the commonly available NVMe BIOS modules?

1)I have not inserted any nvme modules into the BIOS. I am using default/stock asus bios.

2) My bios does not see the ssd. Upon installing Win10 on it, (yes win detects it fails). So, I need a bios mod to support efi. Which why I asked the question :) PCI legacy bios pass/ efi compatible fail, not supported. In all the details.

I've uninstalled samsung NVMe driver and system asked to reboot , i did and after i couldnt boot(blue screen) and had to format e reinstall windows again. Unplugged my samsung 850 evo plus my mechanical hard drive and put my 950 pro in my pcie 3.0 x16 as you told me. Now i did a benchmark with base windows 10 NVMe drivers and i got this results. Seems better now but what should i do now? I mean, i have only one 3.0 x16 and i need it for my discrete gpu. Before buying 950 pro ssd i read that 2.0 x16 should be like 3.0 x8 or x4, so why isn't working like expected also on 2.0 port?

Edit: Installed also magician and samsung NVMe drivers to see if something would change but im getting the same results

You should always use the "update" option, but never use the "uninstall" option, if you want to change a storage driver. You can do it by doing a right click onto the related "Storage Controller" and choosing the "Update driver software" option.

Yes, my bad but at the end i didn't solved. I mean, i still don't know why on my pcie 3.0 x16 it runs at full speed both tried using first windows and then samsung NVMe drivers, so i can exclude driver issues. Now that i've plugged it back on my 2.0 x16 i have again only 800mb/s instead of 2200/mbs random reading. There is also people claiming in the internet that they are running on pcie 2.0 x4 with the same adapter and getting full speeds while mine is stuck at low speeds

Zitat von sinofliberty im Beitrag #866I have followed the instructions, can you check if it is right:

The screenshot looks fine.

ZitatMy source size is 0002A06 unlike in a guide which has 00002A04. Although, I did use different bios version than the guide`s.

Since the modules are compressed within the BIOS in a different way (depending on the available space within the BIOS), the shown size of the inserted compressed module may vary, although the uncompressed files are identical. That is nothing to worry about.

After flashing the BIOS(the BIOS flash was successful according to the message in the end). I unplugged all the drives, put in intel ssd, set boot option from uefi stick where i load the OS. And lastly, in Pci section I selected EFI compatible, but when restated i was presented with the asus logo screen that showed press del. to enter bios. Unfortunately i could not get anywhere and was stuck on it, like when i used stock bios.

On the other hand, pci drive was detected as PARA: so at least there is an entry about it, unlike before.

Marvel, jmb controllers are disabled in the bios. I have gtx 1070/ 2600K. I used uncompressed for normal insertion module.
